The REPORT procedure combines features of the PRINT, MEANS, and TABULATE procedures with features of the DATA step in a single report-writing tool that can produce a variety of reports. A detail report contains one row for every observation selected for the report. Each of these rows is a detail row . A summary report consolidates data so that each row represents multiple observations SAS Techies 2009 11/13/09

PROC REPORT Statement BREAK Statement BY Statement - By Group processing CALL DEFINE Statement COLUMN Statement - Specify the columns in the report COMPUTE Statement DEFINE Statement ENDCOMP Statement FREQ Statement - Freq statistics LINE Statement RBREAK Statement WEIGHT Statement - calculating weighted statistics SAS Techies 2009 11/13/09

break after sector / ol summarize suppress skip; Break: Produces a default summary at a break (a change in the value of a group or order variable). The information in a summary applies to a set of observations. Rbreak: Produces a default summary at the beginning or end of a report or at the beginning or end of each BY group. SAS Techies 2009 11/13/09 Double overline each value DOL * Double underline each value DUL * Overline each value OL * Start a new page after the last break line PAGE Write a blank line for the last break line SKIP Specify a style element for default summary lines, customized summary lines or both STYLE= Write a summary line in each group of break lines SUMMARIZE Suppress the printing of the value of the break variable in the summary line and of any underlining or overlining in the break lines in the column containing the break variable SUPPRESS

CALL DEFINE ( column-id | _ROW_ , ' attribute-name ', value ); Sets the value of an attribute for a particular column in the current row. Used heavily for Traffic lighting and many formatting purposes SAS Techies 2009 11/13/09 Attribute Description Values BLINK Controls blinking of current value 1 turns blinking on; 0 turns it off COLOR Controls the color of the current value in the REPORT window 'blue', 'red', 'pink', 'green', 'cyan', 'orange', 'black', COMMAND Specifies that a series of commands follows a quoted string of SAS commands to submit to the command line FORMAT Specifies a format for the column a SAS format or a user-defined format HIGHLIGHT Controls highlighting of the current value 1 turns highlighting on; 0 turns it off RVSVIDEO Controls display of the current value 1 turns reverse video on; 0 turns it off STYLE= Specifies the style element for the Output Delivery System See Using the STYLE= Attribute

Transport files are created to migrate SAS datasets between platforms (Unix, MVS, Windows) and continue using the same SAS Data Sets as simple transfer of true SAS Data Sets between operating systems will corrupt them. To accomplish the transfer of SAS Data Sets from one operating system to another it is necessary to convert the data set into "transport" format (Proc CPort) move, send or carry the data in "binary" (i.e., non-translated) format to the operating system running the other Version convert the transport data set back into a SAS Data Set (Proc Cimport) Transport files are sequential files that each contain a SAS data library, a SAS catalog, or a SAS data set in transport format. The transport format that PROC CPORT writes is the same for all environments and for many releases of SAS. SAS Techies 2009 11/13/09

PROC CIMPORT ( only created by Proc CPort ) restores the transport file to its original form as a SAS catalog, SAS data set, or SAS data library. SAS Techies 2009 libname newlib 'SAS-data-library'; filename trans2 'transport-file' host-option(s)-for-file-characteristics; proc cimport catalog=newlib.finance infile=trans2; select loan.pmenu loan.scl; run ; 11/13/09

External data sources can include Microsoft Access Database, Excel files, Lotus spreadsheets, and delimited external files (in which columns of data values are separated by a delimiter such as a blank, comma, or tab). Unix SAS does not read Excel, MS Access files…. Only .csv or tab delimited. SAS Techies 2009 11/13/09

External data sources can include Microsoft Access Database, Excel files, Lotus spreadsheets, and delimited external files (in which columns of data values are separated by a delimiter such as a blank, comma, or tab). Unix SAS does not write to Excel, MS Access files…. Only .csv or tab delimited. SAS Techies 2009 11/13/09

PROC PRINTTO The PRINTTO procedure defines destinations for SAS procedure output and for the SAS log. By default, SAS procedure output and the SAS log are routed to the default procedure output file and the default SAS log file for your method of operation. SAS Techies 2009 11/13/09 To do this Use this option provide a description for a SAS log or procedure output stored in a SAS catalog entry LABEL= route the SAS log to a permanent external file or SAS catalog entry LOG= combine the SAS log and procedure output into a single file LOG= and PRINT= with same destination replace the file instead of appending to it NEW route procedure output to a permanent external file or SAS catalog entry or printer. PRINT=

PROC RANK < option(s) >; BY <DESCENDING> variable-1 <...<DESCENDING> variable-n > <NOTSORTED>; VAR data-set-variables(s) ; RANKS new-variables(s) ; The RANK procedure computes ranks for one or more numeric variables across the observations of a SAS data set and outputs the ranks to a new SAS data set. PROC RANK by itself produces no printed output. SAS Techies 2009 11/13/09

The SUMMARY procedure is very similar to the MEANS procedure except for -- By default, PROC SUMMARY produces no display output, but PROC MEANS does produce display output. If you omit the VAR statement, then PROC SUMMARY produces a simple count of observations, whereas PROC MEANS tries to analyze all the numeric variables that are not listed in the other statements SAS Techies 2009 11/13/09

PROC TRANSPOSE <DATA= input-data-set > <LABEL= label > <LET> <NAME= name > <OUT= output-data-set > <PREFIX= prefix >; BY <DESCENDING> variable-1 <...<DESCENDING> variable-n > <NOTSORTED>; COPY variable(s) ; ID variable ; IDLABEL variable ; VAR variable(s) ; Proc transpose data= some out=something prefix=sm; By CID; Var TRx; Id yrmo; Run; The TRANSPOSE procedure creates an output data set by restructuring the values in a SAS data set, transposing selected variables into observations. If no var statement then transposes All Variables. The TRANSPOSE procedure can often eliminate the need to write a lengthy DATA step to achieve the same result. Further, the output data set can be used in subsequent DATA or PROC steps for analysis, reporting, or further data manipulation. SAS Techies 2009 11/13/09

We will cover this at a later date!! What it does? We can develop a template that we can apply to enhance the appearance of an listing output. Adjusting the header, width, colors… similar to what a proc report call define statement highlighting can do. The TEMPLATE procedure enables you to customize the appearance of your SAS output. For example, you can create, extend, or modify existing definitions for various types of output: styles tables columns headers footers tagsets ODS then uses these definitions to produce formatted output. You can also use the TEMPLATE procedure to navigate and manage the definitions stored in templates stores. Here are some tasks that you can do with PROC TEMPLATE: edit an existing definition create links to an existing definition change the location where you write new definitions search for existing definitions view the source code of a definition SAS Techies 2009 11/13/09

PROC DATASETS <option(s)>; AGE current-name related-SAS-file(s) APPEND BASE=<libref.>SAS-data-set <DATA=<libref.>SAS-data-set> <FORCE>; AUDIT SAS-file <(SAS-password)>; INITIATE <AUDIT_ALL=NO|YES<GENNUM= integer>)>; SUSPEND|RESUME| TERMINATE; CHANGE old-name-1=new-name-1 CONTENTS <option(s)>; COPY OUT=libref-1 <DATECOPY> <FORCE> <IN=libref-2> EXCLUDE SAS-file(s) SELECT SAS-file(s) DELETE SAS-file(s) EXCHANGE name-1=other-name-1 MODIFY SAS-file <(option(s))> FORMAT variable-list-1 <format-1> IC CREATE <constraint-name=> constraint IC DELETE constraint-name(s)| _ALL_; IC REACTIVATE foreign-key-name INDEX CENTILES index(s) INDEX CREATE index-specification(s) INDEX DELETE index(s) | _ALL_; INFORMAT LABEL variable-1=<'label-1'|' '> RENAME old-name-1=new-name-1 REPAIR SAS-file(s) SAVE SAS-file(s) The DATASETS procedure is a utility procedure that manages your SAS files. With PROC DATASETS, you can copy SAS files from one SAS library to another rename SAS files repair SAS files delete SAS files list the SAS files that are contained in a SAS library list the attributes of a SAS data set, such as the date when the data was last modified, whether the data is compressed, whether the data is indexed, and so on manipulate passwords on SAS files append SAS data sets modify attributes of SAS data sets and variables within the data sets create and delete indexes on SAS data sets create and manage audit files for SAS data sets create and delete integrity constraints on SAS data sets.

The only difference between the APPEND and many other procedures and the APPEND (and similar) statements in PROC DATASETS is – the default for libref in the BASE= and DATA= arguments. For PROC APPEND, the default is either WORK or USER. For the APPEND statement, the default is the libref of the procedure input library. SAS Techies 2009 11/13/09

CATALOG DATASETS PLOT PMENU TRANTAB GCHART RUN-group processing enables you to submit a PROC step with a RUN statement without ending the procedure. You can continue to use the procedure without issuing another PROC statement. To end the procedure, use a RUN CANCEL or a QUIT statement. SAS Techies 2009 11/13/09
